BQ2002CPN

Battery Chargers Overview

The BQ2002CPN is a low-cost CMOS battery-charge controller designed for NiCd and NiMH applications. It provides reliable charge termination using negative delta voltage (dV/dt) and peak voltage detection methods. The device operates within a temperature range of 0°C to +70°C and features an operating supply current of 500 µA. Packaged in an 8-pin PDIP, it serves as a dedicated fast-charge management IC for portable electronics requiring precise battery charging profiles.

Battery Chargers Procurement Notes

Verify the package type matches the required 8-pin PDIP configuration. Confirm the operating temperature range meets the specific environmental requirements of the target application. Ensure compatibility with the intended NiCd or NiMH battery cell specifications before integration into the design.

Battery Chargers Selection Notes

Select this component when designing circuits for NiCd or NiMH batteries requiring cost-effective charge management. Consider the 500 µA supply current for efficiency constraints. Verify that the 8-pin DIP package fits the available board space and assembly process capabilities.

Battery Chargers Part Context

This part belongs to Texas Instruments' battery management portfolio, specifically targeting rechargeable nickel-based cells. It functions as a standalone controller for fast-charge cycles, distinguishing itself from multi-chemistry chargers by focusing on dV/dt and peak voltage algorithms for safety and longevity.

Battery Chargers Replacement Considerations

Consult official substitution lists for equivalent charge controllers. Verify pinout compatibility and electrical parameters if replacing with other TI models or competitors.
